The surface morphology of the human astragalus (talus) is difficult to represent accurately using landmarks as it is essentially globular in shape. Advances in laser scanning technology allow fast and accurate capture of bone surface morphology. However, methodologies to utilise these new accurate 3D data have not been fully developed. The present study uses canonical sampling of whole surface morphology attained through laser scanning and for the first time applies the technique to analysis of bone morphology. We introduce a new technique for identifying allometric shape characters in whole bone surface morphology. In a sample of adult human astragalus the new technique is successful in identifying and isolating intra-specific allometric shape characters in a bone which typically lacks landmarks and has, consequently, proved difficult to analyse using traditional 3D morphometric methods.
由于人跗骨（距骨）的表面形态基本呈球形，因此使用地标很难准确地表示。激光扫描技术的进步允许快速准确地获取骨骼表面形态。但是，利用这些新的精确 3D 数据的方法尚未完全开发。本研究使用通过激光扫描获得的整个表面形态的规范采样，并首次将该技术应用于骨骼形态分析。我们引入了一种用于识别整个骨骼表面形态中的异速形状特征的新技术。在成人跗骨样本中，该新技术成功地识别和分离了骨骼中的种内异速形状特征，该骨骼通常缺乏地标，因此使用传统的 3D 形态计量方法分析起来很困难。
